Jeremy Greenstock is the Chairman of the strategic advisory company, Gatehouse Advisory Partners, established in September 2010, and Chairman of Lambert Energy Advisory, the oil and gas specialists, since January 2012.

Born in 1943, Sir Jeremy was educated at Harrow School and Worcester College, Oxford. His principal career was with the British Diplomatic Service, ending his career as UK Permanent Representative at the United Nations in New York (1998-2003) and then, after a suspension of his retirement, as the UK Special Envoy for Iraq (September 2003-March 2004).

After three years as an Assistant Master at Eton College, he joined the Diplomatic Service in 1969. The two themes of his career were the Middle East and US/Western European Relations. He studied Arabic at the Middle East Centre for Arab Studies, Lebanon (1970-72) and went on to serve in Dubai and Saudi Arabia in the early 1970s and mid 1980s respectively. From 1974-1978 he was Private Secretary to Ambassadors Peter Ramsbotham and Peter Jay in the British Embassy in Washington, starting a total of ten years spent in Washington and New York on US and Transatlantic business.

After a spell as Political Counsellor in Paris (1987-90), Sir Jeremy came back to London as Director for Western and Southern Europe, the foundation for a number of years’ work on the EU’s Common Foreign and Security Policy and in particular on the Balkans, Cyprus and Gibraltar. He returned to Washington as Minister (Deputy Ambassador) in 1994-95, and was then brought back to London as Director General for Eastern Europe and the Middle East (1995) and then Political Director (1996-98). After chairing the European Union’s Political Committee during the UK Presidency in the first half of 1998, he moved to New York as UK Ambassador to the UN in July 1998. As the UK’s Representative on the Security Council up to July 2003, he worked extensively on matters of peace and security in Africa, the Middle East, the Balkans and South Asia, but particularly on Iraq. He chaired the Council’s Counter-Terrorism Committee from October 2001 to April 2003.

Sir Jeremy left government service in March 2004, after seven interesting months in Baghdad. He became Director of the Ditchley Foundation, the conference centre in Oxfordshire promoting transatlantic dialogue, in August 2004, a position he left in August 2010. He was also a Special Adviser to the BP Group from 2004 to 2010, a Non-Executive Director of De La Rue from 2005 to 2013, a Governor of the London Business School from 2005 to 2008 and Chairman of the UN Association in the UK from 2011 to 2016. He now works concurrently as a Member of the Chatham House Council, as a Special Adviser to the NGO Forward Thinking, as a policy adviser to the International Rescue Committee (UK) and as co-Chair of the European Eminent Persons Group on Middle East issues.
